Greetings Brian,
Yes, I have several of the Chinese coins and the ones that I have are copies. But, many copies of them are out there because you can use them in feng shui good luck charms. I wrote about their meaning in the post or you can look it up on the internet. So as to the charm: take 3 of the coins and tie them together with a red ribbon. Carry it with you in your wallet or put it under a rug at the front door. It is suppose to attract more money. Like attracts like!!
